Diverter valve can pass down heating pipe when in hot water, giving poor hot water, requires new valve or service kit inside valve Earlier plate heat exchangers can pinhole internally, causing mains pressure to go into central heating resulting in 3bar pressure on gauge and discharge from PRV Also check expansion vessel diaphragm has not perished Synchron faulty in diverter valve, it is possible to change just the motor rather than the complete diverter valve, check to see if the valve is motoring from A to B, and then operate the manual lever at the bottom, if the valve holds open once manually operated, suspect the motor Confirm the correct PCB has been fitted, there are several versions, mainly one to fit those boilers with on/off switch, and one without the on/off switch.
